    The HCF and LCM of two numbers are 13 and 455 respectively. If one of the numbers lies between 75 and 125, then that number is

    A)  78                               

    B)  104

    C)  91                   

    D)  117

    Correct Answer: C

    Solution :

    Let the numbers are x and y \[\therefore \]      \[xy=35\times 455\] \[\Rightarrow \]   \[xy=35\times 5\times 13\times 7\] \[\Rightarrow \]   \[xy=65\times 91\] Thus, 91 lies between 75 and 125, then the required number is 91.
